"The withdrawal is over, for all intents and purposes," said one of the officials with direct knowledge of the situation, who requested anonymity to discuss sensitive planning. "It's done." The U.S. currently has roughly 600 troops in Afghanistan, most of whom are Marine Corps and Army personnel providing security at the U.S. Embassy in Kabul, the person said. The rest of the 600 will be based at the Kabul's Hamid Karzai International Airport, said another U.S. official with direct knowledge of the discussions. All of those troops are expected to remain after the pullout is officially complete, The Associated Press first reported last month. Besides the security troops, the only U.S. military personnel left to withdraw by the Sept. 11 deadline Biden set in May are Gen. Scott Miller, the commander of U.S. Forces-Afghanistan, and a handful of staff, the two officials said. U.S. Central Command announced on Tuesday that the withdrawal was 90 percent complete, and the last American troops on Friday left Bagram Air Base, the focal point of the U.S. war effort for the last 20 years.
